CHARLES C. RUEGER, OF ANAOOND A, MONTANA TERRITORY. v

ORE-CONGENTRATOR.

SPECIFICATION forming part of Letters Patent No. 382,833, dated -May 15, 1888.

Application filed May 21, 1887.

To all whom, it may concern:

Be it known that I, CHARLES C. RUEGER, of Anaconda, Deer Lodge county, Montana Territory, have'inventcd an Improvement in Ore-Concentrators, and I hereby declare the following to be a full, clear, and exact description of the same. v

' My invention relates to that class of concentrators which are used for the treatment, of ore, sand, and slimes, and technically known as "buddles or roundtables! I The object of my invention is to increase the working capacity of such machines, and at the same time improve the quality of their performance and simplify the machinery re:

tained by a combination of old andnew parts, shown in the accompanying drawings, in which Figure 1 is a plan of the machine. Fig. 2 is a vertical section'or sectionalelevation through the center of the principal parts.

Many details, not essential to illustrate the invention, are omitted.

A is a concave round table, constructed in any approved manner. B is a convex round table similarly made. Both of these tables are affixed toone vertical shaft, a, which is revolved by some suitable driving mechanism, b, at the top.

D is the receiver for the various products flowing from the table A, and at the same time it serves as a feeder for such of theseproducts as are to be rewashed on the table B. This trough or receiver D is stationary and rests on a suitable frame, d, suspended to. beams overhead. The products from the table B pass onto the cone 0, which presents to them a very much larger surface, and therefore greatly decreases the forceof the currents, so that ore particles which have been swept from the tables A and B will deposit and can be treated under conditions which favor their separation from barren matter.

These objects are at- Serial No. 239,023. (No model.)

This outside cone, 0, therefore, does the finishing or tailings work in a direct and simple manner,

without the intervention of more or less complicated mechanism because the buddies A r and B perform the office of feeders, distributers, dead-heads, 8pc.

As the cone 0 remains stationary, the point or section of discharge for any assumed pro duct travels around the periphery. For this reason one of the arms E of the tableB is extended beyond the periphery of the cone 0 and carries at the end atrough, I, the purpose of. which is to bridge the sluice F, so that the concentrated product from the cone Ocan' be delivered into the tank G. The barren tailings drop into the sluice F. The arrangements for manipulating the various products from the tables A and B are not fully shown, because immaterial to an understanding of the nature of the invention claimed.

Having thus described my invention, what I claim as new, and desire to Patent,- is- 1. The concave table, the underlying con-. vex table, and means for rotating said tables, in combination with the stationary receiver .D and the stationary cone 0, substantially as herein described.

2. A revolving concave upper table and a revolving convex lower table, in combination witha convex stationary cone onto which the orepulp is fed by the tables, substantially as described.

In witness whereof I have hereunto setmy Witnesses:

WM. READ, WM. K. SLOAN.
